Application September 10, 1947, Serial N0.'7 73,17 3 I 4 c ai s, (.01. tetrainvention relates to a pillowdelivery slide stop bracket for typesetting machines.

It-is an object of the present invention to pro vide an adjustable spring cushion slide stop bracket for use adjacent the. end of a track for the line delivery slide of a typesetting machine.

Other objects of the present invention are to provide a spring cushion stop for the line delivery slide which will cause the slide to come to a slow stop and to eliminate the breakage of matrices which often results from the shock which the delivery slide receives when coming to an abrupt stop on the present machines. The stop also pre vents loose lines of matrices; prevents metal from squirting between matrices, and makes a smoother operation of the delivery carriage mechanism.

A further object is to provide a stop wherein there is provided a soft spring to take up the initial shock and then a final cushioning arrangement which comes into play to absorb the final shock.

Still further objects of the invention are to provide a spring cushioning device for a line delivery slide of a typesetting machine which is of simple construction, easy to install upon the slide track, inexpensive to manufacture, easily adjustable and efiicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanyin drawing, in which Fig. 1 is a perspective view of my spring cushioning device mounted upon the track for a line delivery slide of a typesetting machine.

Fig. 2 is a longitudinal cross-sectional view taken through the track and looking in plan upon my spring tensioning device.

Fig. 3 is a side elevational view of my spring cushioning device.

Fig. 4 is a transverse cross-sectional view taken generally on line 44 of Fig. 2.

Fig. 5 is a transverse cross-sectional View taken through the device and on line 55 of Fig. 2.

Referring now to the figures, Ill represents a track for a line deliver slide of a typesetting machine, the end of which is open and into which there is extended and connected my sprin cushioning device Operable in the track is a line delivery slide I?! which is adapted to carry mat rices and which is adapted to abut my spring cushioning device II.

The attachment of the spring cushioning device H with the track II] is eflected by a bolt 13 which enters a longitudinally extending lug or portion IA of a main body part l5 of the spring ushionin device. order to ke p thesprin u h ning de ice from. pivotin on. the bo t. l3 there is inserted. a pin it which enters an 01331.1?

ns t e track and anopening inthe p j tion "l. The body pa t-l5 is; intern lly t readed ndicated at H andthroueh thisthereis e te ded a screw |8 which can be adjusted therethrough. This screw I8 has a central hole l9 therein through which extends a rod 2| having a head 22 adapted to be abutted by the delivery slide I2. The opposite end of the rod 2| is threaded at 23 to receive lock nuts 24 for retaining a plate 25 to which are connected springs 26. The forward ends of the springs 26 are connected to a plate 21 retained on the screw l8 by a lock nut 28. Accordingly when the head 22 is struck by the delivery slide. the shock will be absorbed lightly by the tension springs 26.

On the rod are disposed concaved washers or spring elements 3| which will also assume a part of the shock as the rod 2| is pushed through the threaded member l8. These washers 3| are arranged in pairs with their curved inner faces opposing each other and the pairs are spaced by spacing washers 32.

In order to give additional resistance to the outward movement of the rod 2| there is provided on the rod a plate 34 which is retained against displacement thereon by lock nuts 35 and this plate is extended between side pieces 36 which are held together by a bolt 31 and nuts 38. The ends of these side pieces 36 are fastened by screws 39 to the body IS. A spring 4| is extended between the ends of the side pieces 36 whereby to retain the pieces 36 in frictiona1 engagement with the sides of the plate 34 and to limit the return movement of the rod 2| to take up the shock as the delivery slide has come to rest and permitted to be returned.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

I claim:

1. A cushioning device for a line delivery slide of a typesetting machine comprising a body member having means thereon for the attachment of the spring cushioning device to the track of the line delivery slide, a threaded opening extending through the body, a threaded member in said opening and adjustable axially therethrough, said threaded member having a central hole, a rod slidable through the central hole of the threaded member, a plate extending from the rod, a secg a ond plate adjustable on the threaded member, spring means connected between the plates on the rod and the threaded member to take the shock of the delivery slide upon the rod, and other spring means on the rod ahead of the body memher, a head on the rod adapted to abut the other spring means for also absorbing shock received from the line delivery slide. p

2. A cushioning device for a line delivery slide of a typesetting machine comprising a body member having means thereon for the attachment of the spring cushioning device to the track of the line'delivery slide, a threaded opening extending through the body, a threaded/memher in said opening and adjustable axially therethrough, said threaded member having a central hole, a rod slidable through the central hole of the threaded member, a plate extending from the rod, a second plate adjustable on the threaded'member, spring means connected between the plates on the rodand the threaded member to take the shock of the delivery slide upon the" rod, and other spring means on the rod ahead of the body member, a head on the rod adapted to abut the other spring means for also absorbing shock received from the line delivery" slide, side pieces extending rearwardly from the opposite sides of the body, a plate connected to the rod and adapted to have its ends engage with the side pieces on the body member to frictionally prevent the sudden return of the rod upon the slide coming to rest or removed from the spring cushioning device, spring tension means extending between the side pieces toretain them upon the edges of the friction plate.

3. A spring cushioning device for a line delivery slide of a typesetting machine as defined in claim 1 and said spring means on the forward end of the rod comprising convex washers arranged in opposing relationship and in pairs and with spacing elements between the same.

4. A spring cushioning device as defined in claim 2 and said plates on the rod and upon the adjustable threaded member being adjustable thereon and lock nut means for each of the respective plates for securing the same in locked position respectively on the rod and the adjustable threaded member.
